the washington post is looking at the current votes counted. the shaded parts of the bar are the states where they are winning, so trump is currently ahead in enough states to win the EC. So as it stands, he would take Wisconsin (10), Michigan (16), Pennsylvania (20), North Caroline (15, but this one is very close atm) and Georgia (16) =77
I am aware that the votes that are still to be counted are the votes by mail, which are more likely to be in favour of Biden (hence Trumps claim to stop counting). But as it stands, Trump is ahead.
